我们的萤光探伤工作,过去一直是按照苏联BMAM“№412-55检验零件用的萤光方法”生产说明书进行的。这是一种煤油、滑油组成的萤光液。由于它发现缺陷的灵敏度很低,满足不了高强度有色合金制件、非磁性材料及部分无法进行磁性探伤的零件表面质量检验的需要。我们遵循伟大领袖毛主席关于“在生产斗争和科学实验范围内,人类总是不断发展的,自然界也总是不断发展的,永远不会停止在一个水平上。”的教导,针对用老的萤光探伤方法不能满足生产需要的情况,进行了一些革新试验。经过初步试验摸索,我们试制了二种具有较高灵敏度的萤光液。这二种萤光液,通过几年来的实际使用,除了用于有色合金和
Our fluorescent testing work was done in the past according to the production instructions of the Soviet Union’s BMAM “№ 412-55 fluorescent parts for inspection of parts”. This is a kerosene, oil composition of the fluorescent liquid. Because it found the sensitivity of defects is very low, can not meet the high-strength non-ferrous alloy parts, non-magnetic materials and parts of the surface can not be magnetic flaw detection testing needs. We follow the example of Chairman Mao, the great leader, that “in the struggle for production and in the scope of scientific experiments, human beings are constantly evolving, nature is always evolving, and never stops on a level.” For the purpose of using old The fluorescent detection method can not meet the production needs of the situation, conducted some innovative experiments. After a preliminary trial and error, we trial-produced two kinds of high-sensitivity fluorescent liquid. These two kinds of fluorescent fluid, through the years of practical use, except for non-ferrous alloys and
